Some of their ZombieTech podcast is available on YouTube (along with First Spin and Patch Bay, see the playlists to find grouped series). Note that Rabbithole is the name of their hackspace as well as the video series documenting project creation. Episode 200 has the violin we discussed.

We seem to have talked about a lot of other people on the show, especially shared friends and past Embedded.fm guests (some of whom were on ZombieTech).
